[Snort-users] Specific rule for bandwidth

I would like to use "stream_size" as a bandwidth controller. Thus I created this rule to test its functionality:
alert tcp EXTERNAL_NET any -> HOME_NET any (msg:"WARNING! Session bandwidth > 8 bytes"; stream_size:both,>,8"; sid:1000000001;)
I would like to know if "stream_size" is reset when the alert is triggered or it still count the number of bytes observed?
The doc says : "The stream size keyword allows a rule to match traffic according to the number of bytes observed, as determined by
the TCP sequence numbers." It doesn't pinpoint this aspect and I'm not about my bandwidth test.
